PHOTOGRAPHING AND DEVELOPING APPARATUS.

Application filed June 11, 1914.

To all whom it may concern:

Be it known that I. GEORGE C. BEIDLER, a citizen of the United States ofAmerica, and resident of Rochester, in the county of Monroe and State ofNew York, have invented certain new and useful Improvements inPhotographing and Developing Apparatus, of which the following is aspecification.

This invention relates to photographing and developing apparatus andparticularly to that type of apparatus embodying means for exposing filmto light, severing the portion of the film exposed after it ismechanically drawn from the means for exposing it to light, the cuttingof the exposed portion of the film from the remainder of the film web,and means for developing the section of the film exposed.

An object of the present invention is to provide means for delivering anexposed section of film to a receptacle which may contain fluid adaptedto act on the coated surface of the film, such as developing solution,and novel means for drawing the fil'm from the said receptacle and forsevering the same; the invention furthermore consisting in means forsubjecting the developed film to the action of a fluid contained inanother receptacle to which the film is delivered after it is removedfrom the first receptacle, novel means being provided for submerging thefilm therein to insure proper contact of the liquid with the said filmand for other purposes, all of which mechanism is preferably containedwithin a light-proof casing, capable of excluding actinic rays of light,during the time the mechanism is operating for treating the film.

A further object of this invention is to provide novel means forsubjecting film to the action of fluid. the provision of means forsubmerging the film, the provision of means for cutting the film, saidmeans being correlated and associated to effect the development of anexposed film mechanically while the said film is guarded from light.

\Vith the foregoing and other objects in view, the invention consists inthe broad idea to be set forth in the claims during the prosecution ofthe application, the said claims to be of such scope as to giveprotection commensurate with the inventive act in view of the state ofthe art when the said-invention was produced.

In describing the invention in detail, reference will be had to theaccompanying Specification of Letters Patent.

In these drawings, I have shown an inclosure divided into severalcompartments but the manner of forming the compart ments is not materialand may be changed to suit particular requirements. In the presentembodiment of the invention. I have shown a magazine section 20 and areceptacle casing 21, the latter of which is provided with a door 22,hinged at 23, so that access to the interior of the receptacle casingmay be facilitated and the said receptacle casing may be furtherprovided with a hinged end 24.

The receptacle casing is shown as having longitudinally disposedpartitions 25 near the sides thereof, the said partitions formingcompartments 26 adapted to contain operating mechanism which ispreferably constructed of metal so that the said partitions act asshields for these metal parts and protect them against chemicals whichgrief! used in the development or fixing of the The inner surface ofeach side of the receptacle casing has a substantially F-shaped guide 27secured to it and an angle bracket is furthermore secured to the guideplate producing the double guides 29 and 30 for a purpose to bepresently explained. The partitions 25 have slots 31 horizontallydisposed and extending longitudinally to form ways for the passagetherethrough of blocks 33 and 34, slidable on the guides 30, it beingobserved that the said blocks have slots 34 forming clearances for thereception of the said guides. Each block is provided with a socket 35 toreceive the trunnion 36 on the rod 32 so that said rod may rotate,although 1 the rotary action is not essential to its operation. Thepurpose of the rod is to engage and pull film from a receptacle.

As a means for moving the blocks longitudinally of the guides, eachblock has a socket 37 which receives a stud 38 forming a continuation ofone of the link pins 39 of the chain 40, and, therefore, movement of thechain of each block, results in moving the block. The guides 30 act assupports forthe chains in their travel longitudinally of the casing.

A receptacle 41 extends through the bottom of the casing 21 and issupported or suspended by any appropriate means as by the angle irons 42and the said receptacle is adapted to contain fluid which Wlll act onthe coatedsurface of the film, after it has been exposed tolight and inmost instances, the said receptacle isused as a container for developingfluid. At a point above the receptacle 41 or in such position that filmmay be delivered to the receptacle by their action, are film drawingrolls 43 and 44 which may be journaled in any appropriate way in thecasing, one ofsaid drawing rolls, preferably the drawing roll 43 havinga shaft 45 extending beyond the casing andhavlng a crank handle 46applied to it so that the said roll may be turned and as the peripheriesof the said rolls are practically in contact under normal conditions andare adapted to bear against the surface of film when they are caused tocoact for the purpose of drawing the film, the said rolls operate todraw film from the magazine 20 so that said film may be delivered to thereceptacle 41.

The magazine 20 has a front wall 47 .which constitutes a backing for thefilm,

which is drawn over the anti-friction roller 43, journaled near the topof the mechamsm, said anti-friction roller and down into the casing 21containing the receptacle 41.

and the film is caused to travel over Thatportion of the magazine infront of the wall 47 constitutes an exposing chamber in which the filmis subjected to the action.

of light which may be admitted through the bellows 49 and the bellowsframe 50, which latter is fitted to the front portion of the magazine oran extension thereof. The dark slide 51 which may move transversely ofthe exposing chamber is of a type ordinarily employed and is movable inguides 52 and 53 formed in the structure constituting the magazinechamber or an extension thereof.

Theinteri'or of the casing 21 has a supporting means for the ends of astationary knife 54 which knife is stationed with its cutting edge invertical alinement or nearly so, with the contacting surface of therolls 43 and44' so that the film fed between the rolls passes thecuttting edge of the stationary knife and is in position to be out whenthe movable knife 55 is carried into engage: ment or coaction with thestationary knife; Tn order to operate the movable knife it is mounted'onthe spring arms 56 and 57 and said arms are slidably su ported on theguides 29;, it being shown in the drawings,

that the arms have their ends remote from the knife 55 ofiset downwardlywith respect plied to the. said pins under the guides 29 so that thesaid nuts prevent the pins from withdrawing from the slots, but at thesame time allowing free movement of the arm longitudinally of theguides.

The pins 58 and 59 are of such length that they extend into the path oftravel of the studs 62 and 63 projecting from the sides of the chains40, so that movement of the chains is communicated to the knife whenthe, studs encounter the pins.

As a means for operating the sprocket chains, a shaft 64 is journaledtransversely of the casing 21 and near each side of the casing asprocket wheel 65 is mounted on the shaft, and each of said sprocketWheels en.- gages one of the sprocket chains 40. Near the opposite endof the casing 21, stub shafts 66 and 67 are journaled in the sides ofthe casing, one of which stub shafts being on each side. The stub shaft66 has a sprocket wheel 68 and the stub shaft 67 has a sprocket wheel69. The stub shaft 67 extends through the casing and has a crank handle70-by which the stub shaft is turned. By reason of the connection of thesprocket chains with the sprocket wheels, turning of the crank handlewill result in moving the sprocket chains in unison and as the blocks 33and 31 are connected to the chain, motion of the chain is imparted tothe blocks and consequently to the rod 32.

\n arm 71 is mounted to freely rotate on one. of the stub shafts and thearm has two lugs 72 and 73 spaced apart for receiving a stud 7'1projecting from the side of one of the sprocket chains. so that as thesprocket chain moves bacluvard and forward, the stud 71 engages one ofthe lugs 72 or 73 and partially rotates the arm 71 according to thedirection of movement of the chain. A link 75 is provided for the arm 71and has one end pivotally mounted on a stud 76 projecting from the faceof the arm. The end of the link 75 remote from the arm is connected by apivot 77 with the lever 78 which lever is mounted on a fulcrum 79. Oneside of the arm 71 has a pin 80 acting as a stop to limit the rotationof the arm so that the chain may rotate the arm only a predetermineddistance.

The upper portions of the partitions 25 have bearings 80 and 81 forshafts 81 and 8L on which the arms 83 and 84 are respectively mounted.The shafts 81 and 82 have hangers 83 and 84; which are connected to animmersing frame 85 by pivots 86 so that as the arms swing, the immersingframe is moved with relation to the casing. A receptacle 87 ispreferably placed in the casing and is designed to contain liquid suchas a fixing fluid into which the film may be submerged by the immersingframe. The upper ends of the arms 83 and 8+ are connected by a link 85so that motion communicatcd to one arm is communicated to the other arm.and as the arms operate in unison for communicating motion to theimmersing frame, it follows that film delivered to the receptacle 87will be forced into the liquid. As a means for communicating the motionof the arm 71 to the immersing frame or the hangers supporting the same,the link 75 and the lever 78 heretofore described are interposed betweenthe arm 71 and the arms 81. but in addition to this link and lever justdescribed, there is another element interposed between the lever and thearms 8t which it aetuates, the said member comprising a slotted plate88: the. upper end of the lever 78 having a pivot 89 movable in the slotof the plate. The plate 88 has a recess 90 merging with the slot, thesaid recess forming a seat for the pivot- 89 under certain conditions ofoperation. The plate is furthermore provided with a latch 91 mounted ona pivot 92 of the. plate and the said latch has a. shoulder 93 adaptedto engage the pivot 89 so that movement of the lever 78 is communicatcdto the arm as the said lever oscillates. \Vhen the latch is moved fromthe full line position shown in Fig. 9, to the dotted line positionthereof, the lever may oscillate without communicating motion to the arm84 in one direction.

When the latch 91 is out of engagement with the pivot 89 the outwardmovement of the lever 78 is effective to lift the immersing frame, butthe said frame instead of being positively actuated in its descent, isallowed to descend by gravity.

\Vhen the immersing frame is to be held in elevated position, as forinstance, when film is removed from the receptacle, or for any otherpurpose the plate is adjusted with relation to the pivot 89 so that thesaid pivot will lie in the recess or notch 90.

In order to guard the stationary knife 51 from the action of the fluidswhich might be displaced by the immersing frame, the arms -56 and 57 areprovided with a supporting bar 91 and the said supporting bar. carries ashield 95 which partially embraces the knife 54 as shown in Fig. 2; thesaid shield being carried from the stationary knife as the arms 57 aremoved to cause the movable knife to approach the stationary knife.

In the operation of the apparatus, the film 108, a length of which isprojecting into the receptacle 41, is supposed to have been exposed tothe action of light and has been drawn from the exposing chamber and delivered to the said receptacle through the rotation of the feed rollers,heretofore described. Fig'. 2 shows the first or initial position of thedeveloping cutting and conveying apparatus and it will be seen that therod 32 is normally stationed infront of the film 108 and that it is tobe drawn rearwardly to engage the said film and draw it from thereceptacle 11 while the film is being held by the rollers 13 and 14, andthereafter, the said film is to be severed by the actuation of themovable knife with respect to the stationary knife. \Vith thisunderstanding of the mode of operation, rotation of the crank 70 willresult in communicating motion to the shaft 61 through themeduim of thesprocket chain on one side of the case 21 and through the rotation ofthe shaft 64, the sprocket chain on the other side of the casing willlikewise be moved to the same degree. As the crank 70 is to be moved inaclockwise direction initiatively, the rod 32 will be carried by thesprocket chains toward the rear or right hand end of the apparatus asshown in Fig. 2, being thereby caused to engage the film and draw itfrom the re ceptaele 41. Upon movement of the sprocket chains the pin 74of one chain engages the lugs 72 and 73 of the arm 71 and partiallyrotates the said arm so that movement is communicated to the lever 78and through such movement, the immersing frame 85 is lifted from thereceptacle 87 and the hangers 83 and 84 are elevated above the path.

. gagernent or coaction with the stationary knife so that the film isout after it has been drawn by the rod 32 as stated.

The arm 71 is partially rotated by the action of the chain, but in thetravel of the chain, the pins 74: disengage the lugs 72 and 7 3 andcontinue to travel with the chain while allowing the arm to remainstationary with the parts in the position shown in Fig. 11 where the pin80 is in engagement with the link serving to lock the parts againstmovement until such time as the chain is moved in an anti-clockwisedirection, causing the return of the pin 74: into engagement with thelugs 72 and 73 and a reversal of movement of the arm 71 so that theparts are again brought to the position shown in Fig. 2, it beingunderstood that in the anti-clockwise movement of the chains, a studengages each of the pins 58 and 59 to move the arms 56 and 57 to thepositions which they are shown to occupy in Fig. 2. After the parts havebeen brought to the position shown in Fig. 2, the film feeding ordrawing rollers are again operated to feed film into the receptacle andthe operation is repeated.

As has been heretofore stated, it is possible to positively actuate theimmersing frame through the action of the lever 7 8.by causing the latch91 to lock the pivots 89 in the end of the plate 88, but when the latchis in the position to release the pivot 89, the lever 78 moves theimmersing frame in one direction only, that is to say elevates theframe, whereas the frame is allowed to descend by gravity.

' The magazine 20 is provided with any appropriate type of support forthe spool 109 and as the type of spool is immaterial, it is notdescribed in detail.

The plate 88 has an apertured lug 110 in which an adjusting screw 111 isthreaded, said adjusting screw having its end adapted to bear againstthe pivot 89 so that said pivot may be held in the recess of the latch91.

The receptacle 41 has hangers 112 extend ing downwardly to support adrip pan 1-13,

' the said drip pan being provided to receive drippings of materialdischarged from the faucet 114- in the bottom of the receptacle 41, sothat the said receptacle may be conveniently drained.
